' Application filed JanuaryZ, 1891. Serial Ilo.373,878. (llo model) Toall whom it may concern:

' Be it known that we, JOHN F. LYDON, a resident of 'Des Moines, in thecounty of Polk,- and WILLIAM STACY, a. resident of Iowa Falls,

in the county of Hardin, both in the State of the weight and increasethe strength of a fin-' ger-bar, and to prevent the binding of sicklesincident to the bending of finger-bars, and to reduce the material andcost of a finger-bar. Our invention consists in shaping and bending aflat metal plate, as hereinafterset forth, pointed out in our claim, andillustrated by the accompanying drawings, in which Figure 1 is a planview of the blank from 2c which our bar is constructed. Fig.2 is abottom view showing a portion of our finger-bar with guard-fingers fixedthereto. sectional view through the line a: a; of Fig. 2.- A representsa blank or thin sheet of steel or any other metal cut in approximatelythe form shown in Fig.1 and adapted to be bent, as hereinafterdescribed, to produce a fingerbar. In forming the device the outerlongest 3o edges of the blank A are bent, at the place indicated bydotted lines B and B into a right angle relative to the remainder of'theblank' to produce flanges G and 0 Rightangled bends are then made at thepoints indicated by the dotted lines D, D D and D thus bringing theflanges C (1 into proximity Fig. 3 is a.

with each other and their outer edges in contact with the middle portionof the blank to thereby stiffen the bar, as required to prevent tiexion,as shown in Fig. 2. That portion of the blank between the flanges C G isperforated to admit bolts, screws, or rivets to secure the guardstheretc.

F represent guards of common form fixed to the bar by means of bolts,screws, or riv- 5 ets, as shown in Figs. 2 and 3.

.The complete device may be attached to a reaping oimowing machine inany desired common way. The ends of the bar are reinforced and madesolid by fitting pieces H therein, through which bolts may be passed inconnecting the bar with shoes;

From the foregoing description of the device and mode of making thesame' it will be obvious that the weight of a finger-bar is greatlyreduced and the strength thereof increased by reason of the use of sheetmetal.

We claim as our invention- A finger-bar made of a single sheet of metalbent, folded, and pressed to form two tubular sections having anunobstructed space between them, said space being bounded bystrengthening-flanges formed by the sides of the tubular sections thatare adjacent to each other, as and for the purposes set forth.

- JOHN F. LYDON.
